Angioleiomioma de cavidade nasal: relato de um caso e revisão de literatura

Abstract

Li omyomas of the nasal cavity and paranasal sinuses are rare. They make up less than 1% of all leiomyomas in the human body. This is due to the paucity of smooth muscle in the nose. They are classified in three groups: leiomyoma, angiomyoma and epithelioid leiomyoma. Only 15 cases of vascular leiomyomas have been found in the literature. The treatment of choice is surgical excision. Hereby we present a new case and review the literature.

Leiomyoma in the nasal cavity of a dog

“…In the present case, neoplastic cells of smooth muscle origin were closely associated with veins in a pattern reminiscent of a case of nasopharyngeal angioleiomyoma in a dog (Carpenter & Hamilton 1995). Myxoid stroma is otherwise a feature reported in human nasal angioleiomyoma (Campelo et al 2008). These histological features suggest a vascular smooth muscle origin for the tumour.…”

Angioleiomioma de septo nasal

“…He most frequent treatment for nasal septum angioleiomyoma is endoscopic resection with macroscopic margin, and this was the treatment option for this case - excision with macroscopic and microscopic free margins. Vascular leiomyomas are bundles of smooth muscle cells, relatively organized, and permeated by thick wall vessels 4 .…”
